Gerhard Sittig a36b21fb89 fluke-45: drop serial port echo test, was disabled for years
The Fluke 45 driver's ECHO_TEST broke other people's SCPI device
identification and was disabled in 2018-11. Remove the dead code which
is impossible to resurrect. Its purpose was questionable to begin with.

Should users be affected, then the echo would break the identification
phase. The check cannot be done before identification without affecting
other connected devices, cannot be done after the identification either
when that very identification systematically fails. Should a user meet
this condition then applications' logs are available to see why *IDN?
fails, assuming that users are not aware of their serial port or device
configuration. The request's reflection in the place of a response gives
a strong hint.

README

-------------------------------------------------------------------------------
README
-------------------------------------------------------------------------------

The sigrok project aims at creating a portable, cross-platform,
Free/Libre/Open-Source signal analysis software suite that supports various
device types (such as logic analyzers, oscilloscopes, multimeters, and more).

libsigrok is a shared library written in C which provides the basic API
for talking to hardware and reading/writing the acquired data into various
input/output file formats.


Status
------

libsigrok is in a usable state and has had official tarball releases.

While the API can change from release to release, this will always be
properly documented and reflected in the package version number and
in the shared library / libtool / .so-file version numbers.

However, there are _NO_ guarantees at all for stable APIs in git snapshots!
Distro packagers should only use released tarballs (no git snapshots).

------------

Requirements for the C library:

 - git (only needed when building from git)
 - gcc (>= 4.0) or clang
 - make

Please check README.devices for some notes and hints about device- or
driver-specific issues to be aware of.


Firmware
